A proton is the only stable example of a particle composed of three quarks. But inside the proton, gluons, not quarks, dominate.

The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it a reasonable way to make sense of things?

The difference between predictions and observations of the magnetic properties of muons suggests a mystery for the Standard Model.

This is especially true for three key groups.

Yondr CEO Graham Dugoni unpacks the technological zeitgeist in this exclusive Big Think interview covering media ecology, leadership, AI, human connection, and much more.

The big question isn’t whether the Universe is expanding at 67 or 73 km/s/Mpc. It’s why different methods yield such different answers.

50 years ago, Stephen Hawking showed that black holes emit radiation and eventually decay away. That fate may now apply to everything.

The ultimate definition of trauma, explained by leading psychiatrist Bessel van der Kolk.

Even with the best technology imaginable, you’d probably never be able to exist as a consciously aware brain in a vat.

There’s a quantum limit to how precisely anything can be measured. By squeezing light, LIGO has now surpassed all previous limitations.

Unless you confront your theory with what’s actually out there in the Universe, you’re playing in the sandbox, not engaging in science.

Whether you’re a leader looking to ramp up team output or just trying to improve your skill set, hard work alone is not enough.

The multiverse is an idea that has gained a lot of traction in popular culture. But what does science have to say about it?

Memory takes effort, and our brains know it.

Since its observation discovery in the 1990s, dark energy has been one of science’s biggest mysteries. Could black holes be the cause?

Science cannot help us understand or describe first-person experience. Zen koans are a powerful form for helping us reach that description.

Your teams need authentic caregiving, not an insincere plan to merely check all of the well-being boxes.

We know the Universe is expanding, but scientists don’t agree on the rate. This is a legitimate problem.

Yes, the Universe is expanding, but if you’ve ever wondered, “How fast is it expanding,” the answer isn’t in terms of a speed at all.

Holograms preserve all of an object’s 3D information, but on a 2D surface. Could the holographic Universe idea lead us to higher dimensions?

There are a few clues that the Universe isn’t completely adding up. Even so, the standard model of cosmology holds up stronger than ever.

A concept known as “wave-particle duality” famously applies to light. But it also applies to all matter — including you.

First discovered in the mid-1960s, no cosmic signal has taught us more about the Universe, or spurred more controversy, than the CMB.

In the quest to measure how antimatter falls, the possibility that it fell “up” provided hope for warp drive. Here’s how it all fell apart.

We think of physical reality as what objectively exists, independent of any observer. But relativity and quantum physics say otherwise.

The sharpest optical images, for now, come from the Hubble Space Telescope. A ground-based technique can make images over 100 times sharper.

On larger and larger scales, many of the same structures we see at small ones repeat themselves. Do we live in a fractal Universe?

The fabric of spacetime is four-dimensional, with three for space and only one for time. But wow, time sure is different from space!

Too many companies fail to recognize that “the deepest principle in human nature is the craving to be appreciated” — but the solution is easy.

The Vera C. Rubin Observatory in Chile will image the southern sky using the largest digital camera ever built.
